WILLIAM ANTHONY, 0F CLYDE, OHIO.

BTTERY-METER.

To all lwhom it may concern Be it known that I, WILLIAM ANTHONY, a citizen of the United States, residin at Clyde, in the county of Sandusky and tate of 0h10, have invented certain new and useful Improvements in Battery Meters, of which the following is a specification.

This invention relates to instruments used for measuring the energy or electromotlve force of batteries and it has particular reference to the construction of meters of the permanent magnet type and which 1s adaptable for voltmeters, ammeters or volt-ammeters. The object of the inventlon is to rovlde a construction that is eiiicient and re lable for the intended purpose of the instrument; that is durable; and that is economical to manufacture. With this object in view the invention consists in the novel constructlon, arrangement and combination of parts as fully described in the followln specification .and pointed out definitely in t e annexed claims, reference being had to the accompanymg drawings which form a part of the specilication and in which similar characters of reference are employed to designate similar arts. v P In the drawings Figure 1 is a face view of a voltmeter embodying the improvements.

v ention is the construction being almost entlrely die work. The front or face plate 1 is made of non-magnetic metaland has the dial 2 mounted thereon. A portion 1n of the face plate is struck up above the dial. This arrangement allows the moving element or indlcating finger 3 to be made straight and to operate in a arallel plane with the dial 2 for its entire ength, it also provides a clearance chamber 1" 1n which the balance weight 3 is free to oscillate in a plane with the index linger 3. A slot 1 is provided for the projection of the finger 3 and the are of oscillation of said finger is limited by the extremities of said slot.

The pivot staf 4 on which the index finer 3 is fixed is mounted in point bearings 1d 1n the member 1 and 5*. of the supporting bracket 5. The bracket 5 is of non-magnetic metal and not only provides a bearing for the pivot staii` 4, but also furnishes a support for the solenoids 6, being adaptable for the support of one or more solenoids, there beintwo in the embodiment as shown.

he bracket 5 is rst formed with the lower member as shown by dotted line in Fig. 9 and is vattached to the member 1 b punch rivets 1 which are integral wit member 1. In assembling, the pivot staff 4 is placed in position between member 1 and bracket 5, one terminal point of the staff 4 being seated in the bearin 1". The bracket is held firmly in suitab e jaws provided therefor, and the lower member of bracket 5 is up-set or crimped to seat the opposite terminal point of stali' 4 in the bearing 5, the crimping process being such as to ive the proper adjustment to the pivot sta This crimping process maintains the journals or female pivot impressions in a rigid position that is not disturbed by vibration.

rlhe base member 7 is formed with lugs 7 provided with right angle members 7 for supporting the face plate 1, said face plate being attached by screws 8 threaded into the members 7b. The base member 7 is also yprovided with lugs 7 having internally threaded bosses 7 thereon to accommodate screws for attachment of the casin 9 which incloses the working elements an lis provided with a glass cover 10.

The coils or solenoids 6 are mounted on the arms 5b which are preferably lintegral v with the bracket 5. A` permanent magnet 11 is adjustably attachedto the face plate 1 lin the following described manner z-Two f' as a center, said member 11L being adapted v lugs 1t and 1g are formed integral with the for confinement between the lugs 1f and 1S, andbeing held therein by a clamp bolt 12. The magnet 11 is thus made angularly 'adjustable, andthe'endsor poles '1 1: and 11 of said magnet being angular, relative to the body of the magnet, allows a ne adjustment v for causing the soft iron vane 4l on the pivot staff to assume a position in relation tothe solenoids that is most conducive toa uni- .formly divided Scale on the dial which in.- dicates the voltage by the registration of the index finger 3 with said dial.

the solenoids 6 and thebinding posts 13 and 13 through conducting wires, not shown but connecting said solenoids with members 14 and 14, said members 14 and 14 being attached to the base member 7 and connected with thebinding posts 13 and 13", and being insulated from-the members 15 and 16. l

As the functions of the coperating elements as embodied Vin the im roved meter are common to meters of this c aracter, it is not deemed necessary or expedient to en-l cumber the specification witha descriptionof the operation, owing to the fact that the present invention has reference to the novel construction, arrangement and combination and which is 415v manufacture.
